Abstract


This paper presents the results of the research and development of composite gypsum binders (CGB) based on technogenic raw materials in the form of ash and slag mixtures of fuel wastes, which reduces the consumption of Portland cement clinker up to 85% in comparison with traditional composite binders. The optimal compositions of the CGB are proposed. The impact of the type of mineral additives of technogenic origin and superplasticizer on the technological and physico-mechanical properties of the solution and stone based on the CGB is studied.
